Kingman is the new favourite for the 2000 Guineas following an impressive victory at Newbury on Saturday.

John Gosden's colt smashed his opposition in the Aon Greenham Stakes, beating the well-backed Night Of Thunder by four and a half lengths.

The manner of victory eventually saw all firms slash the horse into favouritism.

Stan James went all the way into 6/4, while others went into either 7/4 or 2/1 although it took a while for some to do so.

Sky Bet, Ladbrokes and Paddy Power were among the others to immediately make the horse their favourite for next month's opening Classic of the season, replacing Australia at the head of the market.

However, Boylesports, Betfred and totesport all laid 3/1 before being forced to make similar cuts to their rivals as the cash came in.

Aidan O'Brien's Australia, due to go straight to the QIPCO-sponsored Guineas, was pushed out to a top price of 4/1 by Stan James.

Their Rory Jiwani explained their moves.

He said: "That was a scintillating performance and our immediate reaction was to cut him from 7/1 to 2/1 favourite for the 2000 Guineas. We were bowled over by interest at that price straight away, including one bet of £5,000, and we've had to cut him again to 6/4."

Sky Bet's Michael Shinners, whose firm went 7/4 from 6/1, said: "The vibes for Australia have been very strong through the spring but he'll need to be every bit as good as they say to lower Kingman's colours at Newmarket."

Reaction to Night Of Thunder's run in second was mixed. Stan James cut the Greenham gamble into 8/1 (latter amended to 12s) but Paddy Power were unimpressed and pushed their quote to 25/1.

Master Carpenter delighted some each-way punters by taking third at odds of 80/1.

Earlier on the card, Mutakayyef was beaten in the opener and was left at 66/1 for the 2000 Guineas.

Newbury's 1000 Guineas trial, the Dubai Duty Free Stakes, was won by J Wonder, who landed a significant gamble.

Available at a double-figure price in the morning, Brian Meehan's filly was sent off at 4/1.

She was duly cut as short as 12/1 for the Guineas following victory over Al Thakhira and the fast-finishing Joyeuse but Ladbrokes and Boylesports were prepared to lay 25s.

Sky Bet were one of those at 12s (from 50s) and their spokesman Shinners said: "She was clearly expected to run well and you had to like the way J Wonder picked up. Both the front two look smart fillies at the very least."

Connections said both the English and French Guineas would be considered in terms of future plans.

Beaten favourite Al Thakhira was pushed out to 25/1 by Ladbrokes and Coral but Joyeuse, a half-sister to the legendary Frankel, was cut to a general 25/1.

Jiwani said: "Joyeuse ran on well for third and we trimmed Frankel's half-sister from 33/1 to 25/1 with an extra furlong set to suit at Newmarket."

At Navan, Fascinating Rock won the Ballysax Stakes and was given 25/1 for the Investec Derby by Paddy Power and William Hill.

Dazzling was a winner on the same card and was duly moved as short as 10/1 for the Oaks, which also takes place at Epsom in June. Sky Bet, however, were unconvinced and dangled 25s.

At Ayr, My Tent Or Yours was beaten into third in the Scottish Champion Hurdle and was duly pushed out to 7/1 by Betfair's Sportsbook arm for next year's Champion Hurdle at Cheltenham.
